R-MDMA
R-MDMA, 4-methylenedioxymethamphetamine (MDMA) isomer, is a 5-HT2A/5-HT2C receptor antagonist with an IC50 of 629 and 61.4 nM. R-MDMA promotes cortical neuron growth. R-MDMA facilitates fear extinction learning and produces antidepressant-like effects in preclinical rodent models. R-MDMA can be used for the researches of post-traumatic stress disorder and depression.

R-MDMA (10 pM-10 μM; 24-72 h) promotes cortical neuron growth[1].
R-MDMA (100 μM; 15 min) induces serotonin efflux from SERT-expressing HEK293T cells[1].
R-MDMA (10 pM-100 μM; 5 min) acts as a moderately potent antagonist at 5-HT2A receptors in HEK293T cells with an IC50 of 629 nM[1].
R-MDMA (10 pM-100 μM; 5 min) acts as a moderately potent antagonist at 5-HT2C receptors in HEK293T cells with an IC50 of 61.4 nM[1].

R-MDMA (12.5-25 mg/kg; i.p.; single dose; 30 min prior to extinction training) facilitates fear extinction learning, producing sustained reductions in freezing behavior in a mouse fear conditioning model[1].
R-MDMA (12.5-25 mg/kg; i.p.; single dose) at 25 mg/kg produces a sustained antidepressant-like effect in the mouse tail suspension test[1].
R-MDMA (20 mg/kg; i.p.; single dose; administered during social interaction training sessions) does not produce a statistically significant social conditioned place preference in mice[1].

Animal Model:C57BL/6J (9-13 weeks old, mixed male and female)[1]
-
Dosage:12.5 mg/kg; 25 mg/kg; 50 mg/kg
-
Administration:i.p.; single dose
-
Result:Decreased locomotion at 12.5 mg/kg.
Increased locomotion at 50 mg/kg.
Caused significantly less time spent in the arena center (increased thigmotaxis) at all doses.
Did not induce head-twitch response at any dose.
Caused transient decrease in body temperature at 30 min post-administration of 25 mg/kg and 50 mg/kg, which resolved by 60 min.
Produced no body temperature changes at 12.5 mg/kg.

Animal Model:Depressant C57BL/6J (9-13 weeks old, mixed male and female)[1]
-
Dosage:12.5 mg/kg; 25 mg/kg
-
Administration:i.p.; single dose
-
Result:Reduced immobility time to a comparable extent to positive control Ketamine (3 mg/kg) at 25 mg/kg.
Did not produce statistically significant antidepressant-like response at 12.5 mg/kg.
Had its antidepressant-like effect blocked when pretreated with 5-HT2 antagonist Ketanserin (HY-10562) (4 mg/kg, i.p., 10 min prior) at 25 mg/kg.
